    Sure there's no power? The PSU can be shut down by other faults in the set such as defective LED backlights.

    Get a schematic for the set and see if you can figure out (1) where to make measurements for the power output and (2) discover where any 'shut-down' signals originate from.

    You might get away with disconnecting the backlight supply wires and seeing if you can see any screen image - use a torch and view at an acute angle in a dark room.
